A) \[\frac{192}{729}\]
B) \[\frac{256}{729}\]
C) \[\frac{240}{729}\]
D) \[\frac{496}{729}\]
Correct Answer: B
Solution :
Given = p = 2q & we know that p+q = 1\[\Rightarrow \]\[P=2/3\] \[P=2/3\] The problem of at least 5 successes \[{{=}^{6}}{{C}_{5}}\,{{P}^{5}}\,q{{+}^{6}}{{C}_{6}}\,{{P}^{6}}\] \[=\,\,\,6\times {{\left( \frac{2}{3} \right)}^{5}}\left( \frac{1}{3} \right)+1\times {{\left( \frac{2}{3} \right)}^{6}}=\frac{25}{729}\]
